This eraser is used on a daily basis by many people. It holds up well to repeated use. We only had one issue when someone pulled out the bottom layer of eraser instead of the top layer. This was user error and not a problem with the eraser. We have purchased several of these in the past.

We have a large whiteboard that I converted into a calendar. I like this eraser much more than the other whiteboard erasers. It does its job and if it doesn't you pull the old one off and start anew. It lasts for a long time. At the end it kind of shifts on the eraser but we bought more this time around to last forever in case they go out of business.

Ghostdusters work well for ceramic whiteboards. It removes the dry ink cleanly, and as each layer of the Ghostduster builds up dry ink, it can be removed and disposed of, leaving a clean surface underneath. To not have to throw out the whole eraser once it's full of ink is more convenient and more long lasting. It works well in combination with spray cleaning the whiteboard regularly.
